Possible vacuum leak
At idle my boost meter does not bounce around but stays at a steady reading of about negative seven or eight. If I am cruising and back off the gas it will drop to negative ten, but when I come to a complete stop it will hover around -7 or -8. Is this a sign of a vacuum leak? It used to bounce around a little until the engine heated up and then settle down, but I first noticed this after I had my Flowmaster 80 series installed. I am having a Magnaflow highflow cat installed in the morning. Is this something I should be concerned about the moment?
